[Xapian-discuss] xapian perl bindings: aborted on numbers

  I went ahead and rebuilt all of indexes from scratch and now the
problem seems to have disappeared.  I used exactly the same scripts,
so I'm a bit confused as to what could possibly be different.  Perhaps
one of the indexes was corrupt or something, although why exactly that
would affect only terms composed entirely of integers I'm not sure?
  Anyway it does not seem to be a problem specific to the perl
bindings so I apologize for the misdirection.
